OUR NATIVE PLANTS. 159 



Among those for ordinary culture, we have Orchis spectabiUs, 

 four inches in height, with four or five white and purple flowers on 

 a stem. 



Arethusa bulbosa has flowers two inches long, of beautiful pur- 

 ple color. 



Another beautiful little plant is Calypso borealis, with large 

 pink and j^ellow flowers. 



The genus Habenaria consists of several species, all having 

 large spikes of flowers, differing in color. Thus H. dilatata, 

 H. blephariglottis, and H. orbiculata are white ; H. psycodes -and 

 H. fimbriata, purple ; H. hyperborea and H. Hookeri, greenish ; 

 H. ciliaris and H, Integra, orange ; and H. cristata, yellow. 



Calopogon pulchellus has very neat pink flowers with yellow 

 lines ou the lip. 



Several of the Spiranthes, or Ladies' Tresses, are pretty plants, 

 with white flowers in a dense spike ; gracilis, cernua, graminea, 

 and simplex are some of the species. 



Epipactis gigantea is a showy plant resembling a Cj'pripedium ; 

 the stems are one foot or more in height, with several large white 

 and purple flowers. 



The Goodyera is a genus of four species with verj^ ornamental 

 leaves, besides the white flowers ; G. repens has small velvety green 

 and white leaves : near to it is the Southern G. quercicola, very 

 little known at present. G. pxibescens is perhaps the best of all, 

 having large dark leaves with numerous white veins ; and of about 

 the same size we have G. Menziesii, with dark green leaves and a 

 large white band in the middle. 



Bletia verecunda and B. apthylla are two show}' plants, with large 

 spikes of ample pui-ple flowers. 



Now we come to the best of the Orchids, namel}', the Cypripe- 

 diums or Lady's Slippers. They are not only the showiest, but 

 also the easiest to cultivate. The most common is C. acaule, with 

 large flowers, usually purple, but occasionally pure white varieties 

 are found. C. pubescens and 0. parvijiorum are pretty much 

 alike, both having large, showy yellow blossoms, produced singly 

 or in pairs. C arietinum has neat little flowers of purplish color. 

 C. montanum bears from one to three white and brown flowers. 

 C. candidum is a neat species with white lip. C. Californicum. 

 has stems with as many as six flowers of light rose and yellow 

 color. The best species is C. spectabile,. with stems two feet high.
